To all whom it may concern: I

Be it known that l, GEORGE D. Moose, a' citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Textile Belting and- Method of i reparing and Treatin the Same, of which the following is a speci cation.

My invention consists of a novel form of belting and of an improved method of making the same.

. My improved method may be divided'into two onerations-first, stretching and softenical treatment, and, second, the treatment thereof with articular chemicals, as herein-. after specific The first or stretching process consists intaking any of the ordinary forms. of textile material suitable for use asbelting, such-as a plurality of la ers of duck or canvas folded on top of each other and stitched to ether longitudinally or len thwise or sudh as canvas in the belt or ia rio woven in a single piece in various thicknesses and widths by use of several warps and fillings; in wetting such material in water, preferably hot; in stretching the same while wet, I and then drying the same under tension. This rocess is so carried out that all tensile stretch is removed, and this process, while stretching the belting longitudinalllly, will not a preciably diminish its width a will only aiiect the thickness. This preliminary process will render the belting very flexible and will stretch or set the fibers in such condition that they will very readily absorb the chemicals, as hereinafter described, the principal ingredient of which is rosin-oil, a product tion 0 resin.

Generally in practice the rosin-oil is mixed with a certain proportion of a drying or oxidizing oil, such as linseed-oil, tofacilitate drying and to impart a firm hard surface to the material. A proportion of about fifty per cent. of linseed-oil is generally used, and the boiled linseed-oil is preferred. When it is desired to color the belting, a sufiicient quantity of suitable coloring-matter is added to the mixture. The beltin which has been previously stretched an dried, is passed that t..-.e

scribed mixture. The mixture in -the tank,-

which originally is a oily mass, is heated As the until it becomes a very thin li uid. belting'passes through the tan it is thorh saturated and impregnated with the the fibers being in such condition mixture will penetrate or saturate every thread thereof. From the tank the belting is drawn out between suitable wringing-rolls and is wound into a soil. it is then unwound and hung in suitable loops and allowed to remain so for several days or until 1 thoroughly dry.

Many difierent forms of apparatus may be devised for putting the previously-described method into practice. I have shown in the accompanying drawings in diagram one convenient form of apparatus which may be used in order to con' ve a clear understanding of my invention.

eferring to said drawings, Figure 1 is a sectional e evation in diagram of the a paratus used in the stretching process. ig. 2 is a detail of the gearing used to drive the winding-drum. Fig. 3 i s a. detail of one of the rollers, and Fig. 4 is a section in diagram ilustrating the apparatus used in the chemical treatment.

The belting B, preferably in the form of a roll or coil, is placed in a tank A, which containswater,whichisheatedbysuitablemeans, as by a coil of steam-pipe 10. This thoroughlywetted belting is then passed over a guideroller 1 1 between a pair of heavy tension-r0llers 12 and 13. A trough 14 is used to carry the drippings back to the tank A. The roll 13 is mounted on pivoted arms 15 and is forced under pressure against the roll 12 by any suitable means, as weights 16. if desired, the roll 12 may have a friction-strap 17- collars 20 20, which'may be set thereon to accommodate different widths of belting. The belting then passes around rotary steam-drums 21 and 22, which are arranged to dry both faces of the belting. The belting then passes around another guiding-roller 23, which has adjustable collars, and is coiled 'upon a drum 24. The drum 24. is driven b owerful gearing-as, for example, by pul ey 25, carrying pinion 26, the pulley 25 and 7 any suitable means, and the speed thereof may be reduced as the coil C gradually increases in size. By this arrangement a heavy tension will be put upon the belting between the rolls 12 and 13 and the coil C. By this apparatus the belting will be wet, put under a heavy tension While wet, and dried and coiled up under tension to permanently stretch and set the fibers, as previously de scribed. The coil or roll 0 of belting thus prepared is then taken, and the end of the belting is led over a guiding-roller 30, downaround other guiding-rollers 31 and. 32, submerged ina tank D, in which is placed the chemical mixture before described. The mixture is heated by a coil of steam-pipes, as E, within the tank or by a series of gas-jets beneath the same. The belting thoroughly saturated with the chemicals then passes between a pair of wringing-rolls 33 and 34, which wring out any surplus of the mixture, then between a pair of heavier wringing-rolls 35 and 36. A trough 37 conducts any surplus of themixture back to the tank D. The belting is then coiled up into a coil F on a drum 38. The belting is then taken and allowed to thoroughly dry, as before described, and is then ready for use. Many other forms of mechanism may be devised for practicing the invention.

Power is applied to the drum 38 by means of an arrangement ,of gears similar to that shown in Fig. 2. B this means thebelting is saturated and coiled up hot under heavy tension, thus insuring perfect and complete stretching.

The advantages of my improved belting and the method of making the same are as follows: Canvas belting is generally made by soaking the stitched canvas in linseed-oil, there being no care taken to insure penetration of the oil into the fibers further than to leave the belting in the oil for several hours, or even several days, provided there is no immediate hurry for the goods. From the oil tanks the belting is passed between wringing-rolls and is then immersed in a bath of thick paint, which will coat only the surface of the belting. In some cases fine sand or other material is added to the paint, with the idea of increasing its frictionalquality. The

belting then passes between a pair of rollers,

WhICl'l squeeze out the excess ofthe paint, and

isthen dried. This process will merely give a final surface treatment to the belting.

The principal feature of my process over those now generally in use is that every fiber or thread of the belting is treated and reached by the chemicals, so that the finished belting search is homogeneous or of the same composition and consistency throughout as distinguished from belting which depends for its efficiency upon a thick surface-coating of dried print.

()ne of the disadvantages of painted. belts is the tendency of the painted surface to crack, peel, and Wear off, thus rendering the belting unfit for use and exposing its unprotected inner layers to the friction of the pulleys and the deteriorating effect of atmospheric influences. This objection is entirely overcome by my invention. My treatment is one which reaches every fiber of the belting, so that as the belting wears the facing and frictional qualities thereof remain practically constant. Furthermore, my chemical treatment insures a quick and perfect penetration throughout the entire belting. There is no part not throroughly saturated. The inside is exactly like the outside, while in the ordinary paint-and-oil belting the inside (especially in thick heavy belting) is frequently not affected at all. In these ainted belts, moreover, the outside is har er and more brittle than the inside. This causes the outside to crack and peel 0H, thus exposing the unprotected innerlayers or plies.

In my improved belting the rosin-oil and drying-oil penetrate every thread, and therefore every thread, in effect, has the proper friction-surface for driving the pulleys and is flexible and permanently set in the proper condition for all kinds of use. There are no hard spots. This insures better wearing qualities, particularly'in places Where belting is exposed to dampness or acid fumes. Where belts prepared by the surface treatment are used in these places, as the surfaces become worn or cracked off the belting will deteriorate rapidly, owing to the penetration. of the dampness or fumes into the unprotected inner layers or plies. In short, belting prepared by my method has the advantage of perfect homogeneity, fiexibility, and a perfect and continuous friction-surfacewhich will last and remain so long as the belting.

itself can be used. The rosm-oil gives a surface to the fibers which I have found in practice effects a very superior and lasting bite or friction on iron or wooden pulleys.

The specific mechanism and steps-for carrying out the broad idea of my invention may be varied without. departing fromthe scope of the claims.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is
